Key Points

  • Doe Run Resources, part of Rennert’s Renco Group, agreed to a $150 million settlement with 1,373 Peruvian plaintiffs alleging lead and other toxic contamination from the La Oroya smelter.
  • The settlement was announced in St. Louis federal court ahead of the first of four bellwether trials in a 19-year-old case; the agreement must be filed and approved by U.S. District Judge Catherine Perry.
  • Plaintiffs claim physical injuries, learning impairments, emotional distress and lost income tied to contamination; Doe Run has denied admitting wrongdoing and said the Peruvian government also bore responsibility for cleanup.

Lawyers for the plaintiffs said on Wednesday that a business controlled by American billionaire Ira Rennert has agreed to pay $150 million to resolve claims brought by 1,373 people from Peru who say they were poisoned by lead and other hazardous substances while growing up near a smelter.

The settlement involves Doe Run Resources, a unit of Rennert’s New York-based holding company, Renco Group, and was announced in St. Louis federal court on Tuesday, the same day the first of four bellwether trials in the 19-year-old litigation was scheduled to start.

Allegations and scope of claims

Plaintiffs accused Doe Run of releasing lead, arsenic, cadmium and other toxic materials from a smelter located in La Oroya, Peru, which a Doe Run subsidiary acquired in 1997. The plaintiffs maintain that the contamination caused a range of harms, including physical injuries, learning impairments, emotional distress, lost income and other consequences.

They also contend that some of the mismanagement that led to these harms took place in the United States, and that this connection supports their pursuit of damages in U.S. courts.

Defendant response

According to the plaintiffs’ lawyer, Jerome Schlichter, Doe Run and the other defendants did not admit wrongdoing as part of the settlement. Doe Run has said the La Oroya smelter contaminated the surrounding area for decades while it was under private ownership and later when the Peruvian government controlled it, and it has asserted that the government "abdicated" its contractual responsibility to perform cleanup.

In a statement, Doe Run Chief Executive Matt Wohl said the company chose to resolve the dispute so it could "put this behind us and focus on what matters - running our business, serving our customers, and investing in new technologies."

Next steps in the courtroom

Schlichter told reporters he expects to file the settlement agreement with the St. Louis court within about seven to 10 days. The accord must receive approval from U.S. District Judge Catherine Perry. The lawyer also said legal fees will be deducted from the settlement amount.

Schlichter characterized the outcome as the result of sustained effort, saying "a 19-year battle can result in success when clients persevere," and noting the significance of people from rural, impoverished Peru bringing their claims to an American courtroom.

Additional context

The settlement names Ira Rennert as the controlling figure of the business. Rennert is 92 years old and is listed with a net worth of $3.8 billion according to Forbes.

Risks

  • Court approval risk - The settlement requires approval by U.S. District Judge Catherine Perry, and its finalization is not guaranteed until filed and accepted by the court. (Impacts legal and corporate sectors)
  • Fee deductions - Legal fees will be subtracted from the settlement amount, reducing the net recovery available to plaintiffs. (Impacts plaintiffs and legal services sector)
  • Ongoing litigation context - This agreement comes as bellwether trials were set to begin in a long-running case, implying continued legal and reputational uncertainty for parties involved until all procedural approvals are complete. (Impacts mining, metals, and corporate governance sectors)
